Abstract

A contact material for a vacuum interrupter including, a conductive component including at least Cu, and an arc-proof component including at least one selected from the group consisting of carbides of W, Zr, Hf, V and Ti. An amount of the conductive component in the contact material is 40 - 50 vol%, an amount of the arc-proof component in the contact material is 50 - 60 vol%, and a grain size of the arc-proof component is 3 µm or less. A total amount of a sintering activator including at least one selected from the group consisting of Co, Fe and Ni melted in the conductive component is 0.1% or less of the amount of the conductive component.
